ANTIFRICTION BEARING.

Application filed Mayk 25, 1925. Serial No. 32,668.

This invention relates to a presser bearing for machines lof the class shown and describedin a Pat-ent No. 1,560,162, granted to us November 3, 1925, the object thereof being to provide an anti-friction bearing to eliminate undue wear, a. feature being the provision of c-o-acting parts one being mounted in float-ing or free relation with respect to the others toreduc-e to a minimum frictional retarding action of the parts,

especially when maximum pressure is exert- The application of the invention as here-y in shown depicts the pressure head arranged at an angle, but of course it may be horizontal, or only slightly inclined, and its operation will be equally effective.

7e clearly illustrate our invention in the accompanying drawings, which form a part of this specification, and in which drawings similar reference characters are employed indicate like parts, and in which :--l

Figs. 1, 2, and 3, are side elevations of a presser head and its co-acting table, showing our improved bearing in position, the parts being in progressive changed operative positions in the progressive views.

Fig. 4 is a cross section on the line 1-4 of Fig. 2.

Referring at 10, one of a pair of presser heads mounted in the usual guides (not shown) and below the head is a yieldingly mounted j presser table 11, of any desired forn and in 4 19, having side grooves 20, to receive the toV to the drawings, we show the operation of the machine, sheets 12, of

tops of plates 21, which confine thcparts in place against lateral movement.

A lower presser pad 22, is seated in the head 10, and between the pads is a cage 23, having openings 24, and an opening or loop 24a and in the 'openings 24, are rollers 25, slightly larger in diameter than the thickness of said cage, while opening or loop 2.4L, receives a pin or nose 26j, carried on upper pad 19, which acts to draw the cage up the incline from the position shown vin Fig. 3 to that of Fig. 1, on the forward and over swing of the cam and on the downward and backward swing of the said cam the cage follows said pin by the action of gravity, until the pressing action begins, when said pin will travel in the opening or loop 24a,tw1ce as fast as the cage moves over the lower pad, so that the parts will be in theposition shown in Fig. 3 at the end of the back stroke..

The presser head is provided with an opening 27, of a size to accommodate the reciprocal movements ofthe bearing parts.

1t will be understood that modifications of our invention may' be resorted to, vin rthe adaptation thereof to various conditions of use, as properly fall within the scope of the invention claimed.

lV hat we claim as new and desire to secureby Letters Patent is 1. An anti-friction bearing comprising an upper moving` pad and a lower fixed pad, a cage movable on the lower pad and having rollers therein and a loop at the end thereof, said upper pad being provided with endllugs to engage a presser block and a pin adapted to enter the loop ofthe cage to draw it forward after rthe pressing operation.

2. 1n combinationwith a presser head of block, an upper pad having lugs to engage the. block, and a downwardly directed pin, a roller receiving cage having a loop at one end to receive the pin to draw the cage forwardly and upwardly on the forward inoperative stroke `of the presser block, and a lower yfixed padto support the cage and, its rollers.

An anti-friction bearing adapted to op- Grate at an angle to the horizontal in combination with a presser head 11m/'ing un opening in which parte of the bearing reciprocate :md which comprise a, lower pad imbedded in the head, :L roller carrying cage having en end 1loop7 an opper pad having end lugs o engage a presser block and, a pin to ener :md engage the loop to draw the cage for- Ward and upward on the forward inoperaA tive stroke of the presser block prior to the beginning of the downward and backward operative pressing stroke thereof.

In testimony whereof We have afxer'! our signatures.
